Security officials in Afghanistan say a roadside bomb has ripped through a taxi outside the capital, killing at least one civilian and wounding four others.

Tuesday's explosion occurred on a major road in eastern Kabul. It is not clear who planted the bomb.

Separately, the U.S.-led coalition in Afghanistan said one of its soldiers was killed Monday in a fight with militants in Pech district of Kunar province. The soldier's nationality was not released.

The coalition also reports seven militants were killed in Paktika province Monday in clashes with U.S.-led troops, one of whom was slightly wounded.

A statement published in Pakistan, meanwhile, reports the death last week of Younus Khalis, leader of a pro-Taleban faction in Afghanistan who had been in hiding since 2003, when he declared a holy war against foreign forces in Afghanistan.
